Ibrahim, since you did not specify the point of your dive, I'll put you back where you came out of the water, diving to 0605b, where you emerged from the Mess porthole. You use the rest of your first round underwater swimming through the porthole, then the doors, to reach 0404. The old man is still floating in 0303, but now his eyes are open. He has risen into a position that is halfway to upright. As you come in the door, he stares at you, apparently wary of what you might do next.
Enrico will drift into the doorway right behind Ibrahim.
